  The 
  Chinese 
  fauna 
  described 
  in 
  this 
  paper 
  shows 
  clearly 
  its 
  

   strong 
  relationship 
  with 
  the 
  north 
  European 
  Ordovician 
  faunas, 
  

   and 
  especially 
  with 
  the 
  fauna 
  of 
  the 
  Glauconite 
  and 
  Vaginoceras 
  

   limestones 
  of 
  the 
  Baltic 
  provinces 
  of 
  Russia. 
  These 
  two 
  forma- 
  

   tions 
  are 
  essentially 
  equivalents 
  of 
  American 
  faunas 
  included 
  in 
  

   the 
  Mohawkian 
  division 
  of 
  the 
  Ordovician, 
  and 
  we 
  recognize 
  in 
  

   this 
  Chinese 
  fauna 
  several 
  species 
  among 
  the 
  brachiopods 
  which 
  

   are 
  identical 
  with 
  or 
  closely 
  allied 
  to 
  North 
  American 
  Mohawkian 
  

   forms. 
  The 
  fauna 
  presents 
  in 
  its 
  entirety 
  a 
  mingling 
  of 
  Baltic 
  

   and 
  North 
  American 
  forms, 
  although 
  the 
  Baltic 
  element 
  is 
  much 
  

   the 
  more 
  pronounced. 
  In 
  age 
  the 
  fauna 
  is 
  clearly 
  not 
  younger 
  

   than 
  the 
  Mohawkian 
  faunas 
  of 
  North 
  America, 
  and 
  it 
  may 
  be 
  

   safely 
  considered 
  as 
  the 
  essential 
  time 
  equivalent 
  of 
  the 
  Black 
  

   River 
  limestone 
  of 
  North 
  America 
  and 
  of 
  the 
  Vaginatus 
  lime- 
  

   stone 
  of 
  Russia 
  "

  The 
  faunas 
  studied 
  by 
  Girty 
  (46 
  forms) 
  are 
  in 
  the 
  main 
  of 
  

   Upper 
  Carboniferous 
  time. 
  Regarding 
  them 
  he 
  says 
  : 
  

  

  "The 
  faunas 
  of 
  western 
  North 
  America 
  have, 
  as 
  compared 
  

   with 
  those 
  of 
  the 
  Mississippi 
  Valley, 
  a 
  distinctly 
  Asiatic 
  facies 
  ; 
  

   but 
  these 
  Chinese 
  faunas 
  are 
  still 
  distinct, 
  the 
  very 
  features 
  

   which 
  ally 
  them 
  to 
  the 
  faunas 
  of 
  India 
  and 
  China 
  and 
  in 
  which 
  

   their 
  Asiatic 
  affinities 
  chiefly 
  reside, 
  aiding 
  prominently 
  in 
  show- 
  

   ing 
  their 
  alien 
  character 
  to 
  those 
  of 
  even 
  western 
  America"

  With 
  the 
  fullness 
  due 
  to 
  many 
  years' 
  study 
  of 
  the 
  

   Devonian 
  faunas 
  of 
  North 
  and 
  South 
  America, 
  Doctor 
  Clarke 
  

   here 
  describes 
  new 
  collections 
  from 
  Brazil, 
  western 
  Argentina, 
  

   Falkland 
  Islands, 
  and 
  South 
  Africa. 
  Upward 
  of 
  100 
  forms, 
  new 
  

   and 
  old, 
  are 
  discussed 
  and 
  well 
  illustrated. 
  This 
  study 
  has 
  led 
  

   Clarke 
  to 
  reexamine 
  all 
  of 
  the 
  Lower 
  Devonian 
  faunas 
  of 
  the 
  

   southern 
  hemisphere 
  and 
  his 
  results 
  are 
  of 
  great 
  import, 
  not 
  only 
  

   in 
  correlation 
  and 
  faunal 
  assemblages, 
  but 
  as 
  well 
  in 
  paleogeog- 
  

   raphy 
  and 
  the 
  determination 
  of 
  phyletic 
  lines, 
  especially 
  among 
  

   the 
  trilobites 
  and 
  brachiopods. 
  Of 
  new 
  brachiopod 
  genera 
  there 
  

   are 
  Australina, 
  Brasilia 
  and 
  Derbi/ina 
  / 
  of 
  bivalves, 
  Pleuro- 
  

   dapis 
  ; 
  and 
  of 
  trilobites, 
  Calmonia, 
  Pennaia, 
  Phacopina, 
  Probo- 
  

   loides 
  and 
  Schizopyge. 
  

  

  The 
  austral 
  Lower 
  Devonian 
  faunas 
  are 
  characterized 
  by 
  an 
  

   abundance 
  of 
  brachiopods, 
  arcoid 
  taxodont 
  bivalves, 
  and 
  trilo- 
  

   bites. 
  Capulid 
  gastropods, 
  elsewhere 
  so 
  common 
  at 
  this 
  time, 
  

   are 
  practically 
  absent, 
  and 
  the 
  same 
  is 
  true 
  of 
  corals, 
  bryozoans 
  

   and 
  cephalopods. 
  This 
  combination, 
  the 
  author 
  concludes, 
  is
